Just in case, here's what you'd need to do if you find the driver times out on install. Please be cautious with this procedure and do not remove any software devices, as they can be difficult to reinstall without reinstalling the OS.

Start up with only one card in the system

Uninstall ATI drivers through the control panel -> add/remove programs

Reboot into safe mode (hit F8 at boot)

Open a command window with admin privileges

Type in the command prompt:

set devmgr_show_nonpresent_devices=1

start devmgmt.msc

In Device Manager, enable show hidden devices

Uninstall each display adapter in the list (present or non-present/hidden - appearing transparent); by right-click > Uninstall. (Make sure to check the box to remove driver files if possible)

Uninstall any non-present/hidden "PCI standard PCI-to-PCI bridge" devices from system devices. It may also help to uninstall other non-present hardware, but be careful about software and non plug-and-play devices (don't remove them).

Catalyst AI functionality (Catalyst Control Centre only). The basic idea behind Catalyst AI is that it gives the end user the option to completely disable the optimizations in ATI's driver should they feel its necessary.

For those of you interested in specifics, Catalyst AI uses ATI's Texture Analyzer technology (R9600 Series and R4xx series) to optimize performance in any Game/3D application. What about support for older boards? Ati have responded with the following: "We fully support CATALYST A.I. on all R3XX hardware. In fact the R3XX series of products will see an even larger performance boost in Doom 3 than the RADEON X series of products."ATI believe that whilst doing this they maintain the correct image quality and in some cases can even improve IQ. Cat AI does this by analyzing individual textures as they are loaded in order to choose the best and fastest way for them to be displayed. Settings available to the user are Off, Standard and Advanced. By default the drivers are set to Standard. In most cases Standard should be sufficient as it uses less CPU overhead than Advanced and its up to the end user to decide which option works best on their system in each particular game or application. There should be no IQ difference between the two settings however in games where there are frequent texture loads or when using a slower system the extra computations may cancel out the performance increases gained by using the Advanced algorithm.

As well as the texture optimization algorithm there is a second aspect to Catalyst AI and that is the application specific optimizations and tweaks. Examples of these application specific items are forcing Anti Aliasing off in the driver for Splinter Cell or Prince Of Persia because AA doesn’t work in those titles. ATI have informed us that they will never specifically detect a synthetic benchmark with Catalyst AI optimizations however some benchmarks may see improved scores due to using game engines that have improvements within the driver. ATI have also guaranteed that they will only optimize if they can do so without any reduction in Image Quality.

AMD strives to continually improve our drivers and software and we invite you to tell us how. If you are experiencing a problem with our latest driver release, or if you have suggestions on how to make our drivers better, please take the time to submit your feedback.

This program is intended to gather feedback for specific driver releases and not to solicit regular support inquiries. This is NOT the location for support for your product. Support requests will NOT be responded to.
